-- | This function computes the expected coverage percentage and
-- expected number of unique test vectors when using random testing.
--
-- The expected test coverage proportion is:
--  @1 - ((n-1)/n)^k@
--
-- This formula takes into account the fact that test vectors are chosen
-- uniformly at random _with replacement_, and thus the same vectors
-- may be generated multiple times.  If the test vectors were chosen
-- randomly without replacement, the proportion would instead be @k/n@.
--
-- We compute raising to the @k@ power in the log domain to improve
-- numerical precision. The equivalant comptutation is:
--   @-expm1( k * log1p (-1/n) )@
--
-- Where @expm1(x) = exp(x) - 1@ and @log1p(x) = log(1 + x)@.
--
-- However, if @sz@ is large enough, even carefully preserving
-- precision may not be enough to get sensible results.  In such
-- situations, we expect the naive approximation @k/n@ to be very
-- close to accurate and the expected number of unique values is
-- essentially equal to the number of tests.
